9: Communication setting
Refers to the main frequency source by the HC is given by way of communication.
VD120 support Modbus communication mode.
Modbus communication is standard, the other two kinds of communication card is optional, the user
to select according to need, and need to set the parameters F0-23 (communication extension card
type) correctly.
10: Keypad potentiometer
Frequency source is given by keypad potentiometer.

Auxiliary frequency source as a separate frequency given channel (that is, the switching frequency
source selection for A to B), its usage same as the main frequency source A, the method of use can
reference the related description of F0-02.
When auxiliary frequency source used as superposition of given (i.e. frequency source selection for
A+B, A to A+B switch or B to A+B switch), need to pay attention to:
1)
When the auxiliary frequency source for digital given, preset frequency (F0-09) doesn’t work,
the user through the keyboard ▲,▼ key (or the UP/DOWN of multi-function input terminal) for
the adjustment of the frequency.
2)
When the auxiliary frequency source for analog input given (AI1, AI2) or pulse input given, input
100% of the set corresponding auxiliary frequency source range, can be set through by the
F0-06 and F0-07.
3)
When frequency source for pulse input given, is similar to analog given.
Tip: auxiliary frequency source selection B and main frequency source A selection, can’t be set to the
same channel, namely F0-02 and F0-04 can’t set to the same value, otherwise easy to cause
confusion.
